Energy means electricity in this case, and the EU prices are about 2-3x those paid in China AFAIK, for both residential and commercial.

EU is big and prices vary. (Transfer capacity is limited)

Afaik electricity is around 7c/kWh in China. I got 8c/kWh 2y contract a couple weeks ago here in Finland. Though have to add 4c/kWh for transfer to that (no clue if the Chinese prices I could find include that). Commercial prices are less then that (no VAT and possibly lower power tax bracket. The 8c includes all taxes/fees)
